Cistos de erupção em bebê: relato de caso

Abstract

Introduction: The eruption cyst is a benign soft tissue cyst, usually associated with a tooth, with bluish, purple, bluish-black or normal mucosa coloration5. Its etiology is still not well defined, but it is known that in deciduous dentition it can be related to traumatic or inflammatory processes. Objective: The aim of this article is to present a case of eruption cyst in a baby, with emphasis on behavioral management techniques, lesion follow-up and surgical approach. Case report: The case presented is of an 11-month-old baby, whose caregiver reported the presence of an edema on the gingiva in the molar region of the mandible. The treatment option chosen was ulectomy to alleviate the discomfort and difficulty during the child's feeding. Discussion: In general, ECs measure 1 cm x 1 cm and can be present bilaterally or unilaterally; they are more common in the regions of deciduous lower central incisors, permanent first molars, and deciduous upper incisors. However, in this case, all three were located in the region of deciduous molars, but with a size of approximately 1 cm x 1 cm. Two cysts had normal mucosa coloring and one had purple coloring, partially confirming what the literature presents, since it is not so common the presence of EC in the region of deciduous molars. Conclusion: although an EC usually does not require surgical treatment, this may be indispensable in the eruption of teeth. The patient's symptomatology and the delay in tooth eruption are important factors to determine the most appropriate approach, and it is up to the dental surgeon to diagnose, guide the family and, if necessary, intervene in a resolute and atraumatic way.
